USB ethernet adaptors

For olpc development, having network connectivity is a big advantage. Since the current stream software development images do not yet contain a wireless driver, it might be the best solution to use USB ethernet adaptors.

By far not all USB ethernet adapters found e.g., on eBay work "out of the box" with the OLPC (especially the cheap USB 1.1 ones), so let's list devices that are known working here.

The standard image currently contains a driver for the AX8817X chipset (please confirm, this is what my research suggests.) However, this driver is currently broken as of build 193 and requires a updated kernel module in order to work. Please see Bug #549.

These devices have been verified to be compatible:

• D-Link DSB-H3ETX -- pegasus driver, combo hub and ethernet, works for cjb
• D-Link DUB-E100
• LinkSys USB200M - works for ywwg with updated module
• Linksys USB200M ver. 2.1 (verified w/build 303)
• SMC 2208USB/ETH

In theory, these devices should be compatible--please confirm that they are working:

• D-Link DUN-E100 - please confirm that this is working

• NetGear FA120 - please confirm that this is working
• SMC 2209USB/ETH - please confirm that this is working

Bert asks: Wouldn't the driver sources (drivers/usb/net/asix.c) be the ultimate reference to what is supported? Right from the sources:

awk '/products/{if(p)exit;p=1};/^.\/\//{if(p)print}'
drivers/usb/net/asix.c | sed 's|.*//|*|'

• Linksys USB200M
• Netgear FA120
• DLink DUB-E100
• Intellinet, ST Lab USB Ethernet
• Hawking UF200, TrendNet TU2-ET100
• Billionton Systems, USB2AR
• ATEN UC210T
• Buffalo LUA-U2-KTX
• Sitecom LN-029 "USB 2.0 10/100 Ethernet adapter"
• corega FEther USB2-TX
• Surecom EP-1427X-2
• goodway corp usb gwusb2e
• ASIX AX88772 10/100
• ASIX AX88178 10/100/1000
• Linksys USB200M Rev 2
• 0Q0 cable ethernet

And this is only for the AX8817X chipset, there are many more drivers in drivers/usb/net/. In a current kernel config, all of them are enabled (see boot/config-2.6.17-1.2584.olpc1).
